Section two The fifth year an expert meeting on the topic organised by the Association for the Prevention of Torture in January 2014. iii. Children and young people 2013–14 was the second year of operation of the children and young people’s sub-group of the UK NPM. The sub-group is now established as a mechanism for NPM members whose work includes visiting children in detention to exchange information and intelligence and to consider joint work on issues affecting detained children – notably this year, the UK government’s plans to build secure colleges in the youth justice system in England and Wales. The children and young people’s sub-group led work on the NPM’s joint response to the MOJ’s consultation ‘Transforming Youth Custody’ in April 2013, which proposed the creation of secure colleges in England and Wales. The NPM membership set out a series of principles based on the UN Rules for the Protection of Juveniles Deprived of their Liberty (the Havana Rules) which they believed should underpin the design and management of any custodial settings for children. NPM members advocated a more homely, child-centred environment in these settings. The sub-group’s quarterly meetings included presentations on health in secure settings; the use of segregation/isolation practices on children in detention; and police and immigration detention of children. Future meetings were planned to focus on the de facto detention of children, discussing the differing domestic legal context in relation to children and the effects of the Supreme Court’s decision in P (OS) v Cheshire West and another [2014] UKSC 19; and the HMIC‑led thematic inspection of the treatment of vulnerable people in police detention. An evaluation of the sub-group’s first year was also carried out in 2014. It was determined that the sub-group should continue, as it had proved effective, but it should have greater delegated authority to respond on behalf of the whole NPM to emerging issues relating to the detention of children. It was also decided that the sub‑group should take forward work relating to the strategic priority chosen by the NPM for each business year. International scrutiny and collaboration i. Meeting with the UN Subcommittee on Prevention of Torture On 20 June 2013, representatives from HMI Prisons and MWCS, on behalf of the UK NPM, gave a presentation in Geneva to a plenary meeting of the Subcommittee on Prevention of Torture and other Cruel, Inhuman or Degrading Treatment or Punishment (SPT), on the work of the NPM. Most NPMs are single organisations and although some NPMs have a number of members, the number involved in the UK NPM far exceeds that of anywhere else. This brings advantages in terms of resources and experience but complexity in terms of coordination. In this respect, the UK’s multi-member NPM is unique. The purpose of the meeting was to provide the SPT and the UK NPM with an opportunity to consider the strengths and weaknesses of the UK model, what it could learn from or teach NPMs elsewhere and the extent to which the UK NPM is meeting its obligations under OPCAT. This was the NPM’s first meeting with the plenary of the SPT since the UK body was established. In November 2013, the SPT followed up with a letter setting out a series of observations, 31
